[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The present invention determines the travel path of the device through a stable track design, ensuring that the cleaning work can cover the designated area. The I-beam crossbeam provides sufficient strength and stability to ensure that the device will not be deformed or damaged due to its own weight or external force during operation, and can reliably perform cleaning tasks. The single-phase AC drive motor has good control performance and can accurately control the travel speed and position of the device. The nylon wheel transmission not only has a certain elasticity to buffer the vibration during the travel process, but also has moderate friction with the track, which can not only ensure the stability of the device's travel, but also reduce the wear on the track and the device itself, thereby extending the service life of the equipment. The suspended track design combined with the nylon wheel transmission makes the movement of the beam track more flexible and stable, and can adapt to photovoltaic panel areas of different shapes and layouts. The scrubbing roller rotates at high speed driven by the drive motor, which can effectively remove dust and dirt on the surface of the photovoltaic panel, and the wear-resistant material ensures the cleaning effect and service life of the brush during long-term use.

[0016] (2) The present invention uses Siemens PLC as a mature and reliable control system to achieve complex automatic control functions and ensure that the various actions of the device are carried out accurately and in a coordinated manner. The equipment of multiple sensors makes the device highly intelligent and autonomous, able to perceive its own state and surrounding environment in real time, accurately locate and navigate, avoid problems such as deviation or collision, improve the accuracy and efficiency of cleaning work, and reduce the need for manual intervention.

[0017] (3) The present invention can evenly spray water on the surface of the photovoltaic panel through the high-pressure fan-shaped nozzle, forming a larger cleaning coverage area, improving the cleaning efficiency and effect, and ensuring that all parts of the photovoltaic panel surface can be fully cleaned.

The main board adopts Siemens PLC control, integrates the signals from various sensors, and performs automatic operation and logic control. The walking deviation correction sensor 24 monitors the walking state of the device in real time. When deviation is detected, the PLC controls the corresponding drive motor to adjust according to the sensor signal to make the device return to the correct walking track.
